Do you have a datalogger or a wideband?

 

Negative. I don't have anything yet to read or change any of those settings.

 

A wideband and/or datalogger will be needed to make correct changes to the transfer function. Post back once you're able to make those changes and I'll try and help.

 

I appreciate the offer, I'll take you up on that.

How do you like your Eaton? I was thinking of getting this - Eaton Torque Control Products 19660-010 - Eaton Electronic ELocker Differentials - Overview - SummitRacing.com

 

If you have a tweecer and the ability to change the MAF transfer function, just ditch the calibration tube. You don't need it.

You can get the MAF transfer curve dialed in reasonably well using the factory narrow-band O2 sensor. A wideband will make things much easier though.

If the MAF sensor you used is a very popular one, chances are that there will be a published transfer curve on a website somewhere for it that will be nearly "drop in"

 

Agreed, you can get rid of the tube and dial in the transfer function with your software and datalogger and/or wideband.

The locker I have is a limited slip/clutch type. It works very well on the road and at the track. The one thing I'm not a fan of with the E-locker is that it is an open differential when it not energized, but it works very will when it's engaged.

 

I was just told, in another thread, that the wideband sensors are not compatible with my EEC-IV system. So I wanted to learn what type of setup needs to happen for me to take advantage of the wideband? Can you explain please?

 

The wideband has it's own gauge, and you tune it by looking at what your desired A/F ratio is, and what the gauge is reading at a given time.

 

When you say it has it's own gauge do you mean a gauge that comes in a wideband kit or could I use a Cyberdyne air/fuel gauge? I have one of those connected to the stock O2 sensor now, it doesn't look like it gets the best reading from the stock sensor.

 

The wideband comes with its own gauge that you mount in a pod, dash, etc..

Hooking up a gauge to the stock narrowband is pointless. They literally can only read rich of 14.7:1 or lean of 14.7:1.

 

Couple of things...I am still using the narrow band O2 sensor, for now. Once Cyberdyne starts shipping their sensors, I will get one and I should be reading wide band at that point. They say those will start shipping again in early Aug.

Today I got my tweecer and read that it comes blank and that I need to flash it. I have not connected it to my EEC-IV yet (considering where my EEC-IV is mounted in my truck, I am not yet sure if I'll need to relocate it to fit the tweecer). But I do have it connected to the computer and all software installed. So I'm at the point where I need to start learning how to identify the transfer function that will be right for me. Any tip on where to get started for this? I am not sure what factors I need to consider for my new transfer function...I googled it and didn't find much reading, not sure if it's out there.

Thanks.
